Google says it will no longer permit its artificial intelligence, or AI technology to be used in any activities involving weapons. The new policy was one of several newly-launched（最新发布的） "principles" aimed at guiding the company's AI work in the future. The principles are a set of ethical guidelines（伦理准则） covering the company's development and sale of AI technology and tools. Google says it will no longer design or launch AI for weapons or other technologies whose main purpose is to cause harm to people. The principles were announced after more than 4,000 Google employees signed a document calling for the company to cancel an AI agreement with the U.S. Department of Defense（美国国防部）. That agreement involves the use of Google's AI technology for the U.S. military. Other companies could also face pressure from employees or the public if their AI technology is used to develop autonomous weapons（自主武器）. Just as with driverless vehicles（无人驾驶交通工具）, autonomous weapon systems may not be as safe as their supporters promise.
